Power Supply

Power is supplied to the MCB2929 board on your PC via a standard USB-B connector.

The voltage regulators IC2, IC3 and IC7 generate 5.0 Volts DC, 3.3 Volts DC and 1.8 Volts DC, respectively. The Power LED indicates that power is present on the board.


  • IC2, IC3 and IC7 are located under the LCD module.

Caution: Do not attach additional power supplies (such as batteries) while the USB supplies power to the MCB2929. This may harm your PC!
